There are some problems in the DSL filter when you connect to a DSL phone line.
Solutions
If you can not send or receive fax, connect the printer directly to a telephone wall jack to see if the printer
can send a fax. If it works, the problem may be caused by the DSL filter. Contact your DSL provider.
